They sold reasonably well in the international market, but pretty much bombed in the US.
I seem to recall they used vapor phase cooling in their UHF transmitters back in the 1970s.
WSBK-TV in Boston had a vapor cooled UHF transmitter.

TV? We used to refer to those TV sales guys as "purveyors of "mirrors and voodoo". Radio used "real - hot air".

Yeah, I recall that VP cooling was used in the UHF TV rigs. I don't recall ever saw one in operation.......maybe in the final test area however.

I think the big Collins MW TX at the VOA/Bethany station was vapor cooled. Unfortunately that entire site (some 600+ acres) was taken out of service sometime in the 1990s and they put condos on the ground. I heard they moved the TX to a museum and were trying to get it going again.

I bet the copper recyclers made a lot of money off all the spider-web wire antennas strung up at the site.

The nightmares are back!

Nightmares of the GE (low band VHF) TT-42 I had to tend for too many years. Distilled water. Tens of gallons of it. Copper plumbing without end. And an aural transmitter that could remain on-air when the visual was powered down. Oh well, Jack Benny's 1920s electric car is, once again, state of the art. Bring back water cooling - it'll make engineers out of a generation of IT geniuses. With, of course, some pain - but it'll be good for them!
